IMPROVEMENT IN APPARATUS FOR DRYING HUBS.

Specification forming'part of Letters Patent No. 172.592, dated January25,1876 application filed October 6,1875.

To all whom it may concern:

Be it known that I, JOHN URMSTON, of the city of Railway, county ofUnion and State of New Jersey, have invented a new and usefulImprovement in Apparatus for Drying or Seasoning .Elubs, Hub-Blocks,Spokes, &c., which improvement is fully set forth in the followingdescription, reference being bad herein to -the drawings accompanyingthis specification.

The object of my improvement is seasoning or dryingthe specified hubs,blocks, and spokes expeditiously in a dry and Warm air, avoiding themoisture from steam, and also the checking of the interior of the hubfrom the heat from pipes passed through the bore of the hub. It I usesteam it is only to warm the air driven through the hub and hub-blocks.This object I attain by means of a series of square or other shapedtubes, preferring the square form, hav ing as many tubes as the businessmay require. These tubes have their ends inserted in the air-box B, asshown at A. The upper sides of the tubes have perforations, over whichthe orifice in a hub or block is placed,

resting upon the pipe. If desirable, short thimbles can be put in theholes centrally over the holes. Other hubs and blocks are piled uponthose on the pipes, and the air is forced through by an ordinary blower.A receiver, D, is provided and placed between the blower and the air-boxB, with a coil of pipe therein for steam to pass through when deemedneedful to warm the air. I also provide a series of perforations, placedclose together, as at F, upon which fellies can be piled and the airforced between them, and spokes can be placed endwise and a box inclosethem. Airtight apartments are not necessary to thesuccess of theprocess.

What I claim as my improvement is- 1. The series of pipes A and theair-box B, constructed and combined as and for the purpose specified andshown.

2. The heating-receiver O, in combination with the parts A and B.
